Research Interest
I am an Associate Professor in the department of Nutritional Sciences (College of Agriculture and Life Sciences) at the University of Arizona and hold joint appointments in Pediatrics (College of Medicine) and Immunobiology (College of Medicine). I am also part of the mentoring team for the Physiological Sciences and Cancer Biology Graduate Interdisciplinary Programs, which recruit students who are continuing in education. My research interests are concerned with the effects of aging, stress and exercise on the immune system, and the role of adrenergic receptor signaling on immune cell redistribution and activation. Major focus areas include understanding (1) how exercise and other behavioral interventions can offset age-related decrements in the normal functioning of the immune system (immunosenescence), (2) how adrenergic receptor signaling can be used to improve cellular products for hematopoietic stem cell transplantation and immunotherapy, (3) the interplay between the immune and neuroendocrine system during high level human performance and extreme isolation (i.e. space travel), and (3) how persistent virus infections such as cytomegalovirus (CMV) can alter the phenotype and function of T-cells and NK-cells to protect the host from certain hematological malignancies. My current research is supported by NASA, the NIH (National Cancer Institute) and industry. I am a fellow of the American College of Sports Medicine (ACSM) and an honorary board member of the International Society of Exercise Immunology (ISEI). I am an active member of the Pychoneuroimmunology Research Society (PNIRS) and the Society for Immunotherapy of Cancer (SITC) and sit on the editorial board of the following scientific journals: Brain, Behavior and Immunity; Exercise Immunology Reviews (Associate Editor); Immunity and Ageing; American Journal of Lifestyle Medicine.
